Snom D3 Expansion Module

The Snom D3 Expansion Module provides an elegant way to increase the available function keys on D3xx telephones, allowing users to manage a large number of extensions and calls.

Flexibly Programmable Keys

The D3 expansion module features 18 multicolor LED keys which can be programmed with all functions available on Snom phones like line, speed dial, busy lamp field, presence indication, and many more. The call or presence status of your contacts is presented by the D3’s multicolored LED keys at any given time. The high-resolution display provides a perfect visual interface which can be easily configured and labeled via the phone’s web interface or directly on the phone itself.

Ease Of Use

Using the D3 could not be easier: simply connect the USB cable and it’s ready to use. Even power is supplied by the host phone (1). Three D3 expansion modules can be daisy-chained to add up to 54 function keys to your phone. The USB port on the last D3 in the chain can be used to connect other peripheral USB devices like USB headsets or WiFi sticks to the host phone. The D3 is the perfect addition to any D3-series desk phone with a USB port.
